Transformation Rules

Translation: T a, b (x, y) = (x + a, y + b) Ex: Translate (4,-5) = (X + 4, Y + -5) Dilation: D k (x,y) = (kx, ky) (*k is the scale factor) Dilate the figure by a scale factor of ¾ = ( ¾ x, ¾ y)- reduction Dilate the figure by a scale factor of 2 = (2x, 2y) - enlargement Line Reflections: r x-axis( x,y) = (x,-y) r y-axis (x,y)= (-x, y) r y= x ................
